The invention relates to the field of communication, and provides a charging control method, device and system, charging equipment and a battery management system, and the method comprises the steps: building communication connection with the battery management system; when it is detected that the effective gun insertion number is more than two, a first message is sent to a battery management system; the first message comprises first key information of the charging equipment; receiving a second message fed back by the battery management system; the second message comprises a matching result of the first key information and second key information of the battery management system; when it is determined that the matching result is that the first key information is matched with the second key information, target output current is determined, and the current charging task is executed according to the target output current. When the effective gun insertion number is large, the target output current is determined according to the actual capacity of the battery management system and the charging equipment, so that the charging process is high in adaptability and higher in charging efficiency, and the problems that a charging mode based on the national standard charging protocol is low in charging efficiency and poor in adaptability are solved.
Description
technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a charging control method, device, system, charging equipment and battery management system. Background technique [0002] At present, with the increasing popularity of electric vehicles, longer battery life and shorter charging time have become the mainstream direction for the gradual improvement of electric vehicles, especially for some vehicles with high demand for electricity, such as electric work machinery, the demand for charging power is also increasing. [0003] However, the charging method based on the national standard charging protocol, due to the upper limit of the charging current, is difficult to meet the actual charging requirements in the dual-gun or multi-gun charging scenario, and there are problems of low charging efficiency and poor adaptability. SUMMARY OF THE INVENTION [0004] The present invention provides a charging control method...
